Investigation on Family Support System and Willingness of Patients to Participate in Cardiac Rehabilitation after Percutaneous Coronary Intervention.

Objective: We attempt to discuss the relationship between family support and willingness to participate in exercise rehabilitation in coronary heart disease patients after PCI to provide effective guidance for improving the quality of life of coronary heart disease patients after PCI. Methods: By convenient sampling, we selected 90 coronary heart disease patients in cardiology department from September 2021 to January 2022, using general information questionnaire, rehabilitation exercise knowledge, attitude, and behavior questionnaire of patients with coronary heart disease, and the social support scale to investigate the subjects. Results: The total score of knowledge, belief, and behavior in patients with coronary heart disease was 33.02 ± 6.28 points, the social support scale score was 39.63 ± 6.07 points, the multiple linear regression revealed that the educational level, history of cardiovascular disease, and the number of coronary stents of coronary heart disease patients after PCI are the main influencing factors that affect the willingness of coronary heart disease patients to participate in exercise rehabilitation. Conclusion: Rehabilitation exercise knowledge, belief, and behavior scores in coronary heart disease patients are low, and social support is negatively correlated with rehabilitation exercise in coronary heart disease patients.

Neutrophil elastase inhibitory effects of pentacyclic triterpenoids from Eriobotrya japonica (loquat leaves).

ETHNOPHARMACOLOGICAL RELEVANCE: Eriobotrya japonica, a traditional herbal medicine in China and Japan, has long been used to treat chronic bronchitis and coughs. AIM OF THE STUDY: Pentacyclic triterpenoids (PTs), especially ursolic acid (UA), have been found as reversibly and competitively human neutrophil elastase (HNE) inhibitors. However, the limited solubility and poor bioavailability of PTs hinder their clinical use. Crude plant extracts may have a greater activity than isolated constituents of the equivalent dosage. In this study, an Eriobotrya japonica (loquat leaves) extract (triterpenoid composition of loquat leaves, TCLL) with enriched PTs such as UA was prepared. The study aims to compare the HNE inhibitory (HNEI) effect in vitro and the therapeutic effect on acute lung injury (ALI) in vivo between TCLL and UA. MATERIALS AND METHODS: An HNEI activity bioassay was performed with Sivelestat sodium hydrate as a positive control. A lipopolysaccharide (LPS)-induced lung inflammatory model was established to evaluate TCLL's therapeutic effect on ALI in vivo. The absorption of UA in TCLL and in UA alone was determined using a Caco-2 cell uptake model and LC-MS. RESULTS: The IC50 values of TCLL and UA for the HNEI effect were 3.26 ±â€¯0.56 µg/mL and 8.49 ±â€¯0.42 µg/mL (P < 0.01), respectively. TCLL significantly improved the inflammatory cells and inflammatory cytokine production in mice compared with the LPS group (P < 0.05). Additionally, it performed better than the UA alone group (P < 0.05). Moreover, the uptake by Caco-2 cells of UA in TCLL was higher than that in UA alone (P < 0.05). CONCLUSION: TCLL has a significant HNEI effect in vitro and a therapeutic effect on LPS-induced inflammation in a mouse model. Both the effects are more efficient than UA. Improved absorption of PTs in TCLL may be one explanation for these results.

Highly Sensitive and Selective Detection of Amoxicillin Using Carbon Quantum Dots Derived from Beet.

In the present work, we synthesized the carbon quantum dots (CQDs) by one step hydrothermal method using the dried beet powder as the carbon source without additional chemical reagents and functionalization. The as-prepared CQDs are quasi-spherical carbon nanoparticles with diameters of 4-8 nm as well as surface functional groups such as carboxyl and hydroxyl groups, and exhibit good water-solubility, biocompatibility, and strong fluorescence. It is confirmed that amoxicillin (AMO) could enhance the fluorescent intensity of CQDs, the I/I0 showed a linear correlation between the intensity of fluorescence and the concentration of AMO in a broad range. These superior properties render a potential application of the CQDs in biomedical.

[Use W303-1A/hER-ERE-Lac Z to determine estrogenic compounds in traditional Chinese materia medica].

OBJECTIVE: To study the content of phytoestrogen in dissimilarity herbs. METHOD: The activity of phytoestrogen in heat-clearing drugs, drugs for relieving exterior syndrome, diuretic, anastaltics, tonics and astringents were detected based on the recombinant yeast cell (W303-1A/hER-ERE-Lac Z). The estrogenic activity in traditional Chinese materia medica were assayed quantitatively by determining the expression of beta-galactosidase. RESULT: The phytoestrogen concentration (6.35 x 10(-3) nmol x g(-1) E2 equivalent) in heat-clearing drugs was the highest while that in anastaltic and tonic drugs was the lowest, which was less than the detected limit. CONCLUSION: Compared with the other traditional Chinese materia medica, the content of phytoestrogen, which can bind to estrogen receptor, in giant knotweed rhizome, forsythia suspense, ash bark, baical skullcap root and ophiopogonis tuber were higher.
